Dr. Siddiqua completed her PhD. at Cardiff University in geo-environmental engineering. Her research focused on developing a thermal-hydraulic-mechanical model for nuclear waster repository design. Dr Siddiqua did her post-doctoral fellowship at the Geotechnical Laboratory of the University of Manitoba.
As the lead researcher at the CFI-funded Advanced Geomaterials Testing Lab on the Okanagan campus of the University of British Columbia, Dr. Siddiqua and her team research nuclear waste repositories, energy pipelines, chemical stabilization of road subgrade materials, soil nano-particles, soil-water chemistry and the reuse of industry by-products.
Dr Siddiqua has been involved in several Canadian Geotechnical Society committees, and is currently the Chair of the Society’s Education Committee. She is also active with the Women in Science and Engineering organization at UBC Okanagan.
